1973 ep, but filmed in 1972 - introduction of early, French made PR-100 with (not visible here) headlamps placed in the bumper and not above it. Full view of the same vehicle is here (color pic): Link to "www.przegubowiec.com"
I have also picture of identical PR-100, but with different livery, taken somewhere at the south of France. What it was (fsebus?) - pre-serial vehicles, prototypes, or very early ones simply had different lights position? Especially that it seems to be made already in 1972.
Notice in the link is also PR-100 with rear row of seats placed lower, this had to be prototype I believe.
